Hi,
I work with Flow on a Office365 tenant. The Flows all connect to SharePoint in some form or another (all of them has triggers on files changed in document libraries).
I have two Site Collections (modern Communication Sites) - TEST and PROD. I have developed an approval Flow against TEST and have now exported and imported that flow - imported as new instance with a different name and reconfigured the connections).
For some reason, the newly imported Flow does not fire (yes, I have gone through the actions and updated Site URL for all SharePoint-actions, to point to my PROD Site Collection).
I have also created a couple of really simple Flows (triggers on changes in document library files - in two different document libraries), just to see if they get triggered. They don't.
I find this very strange. Is there something I have missed? Is it not supported to have several flows configured to run against different Site Collections or something?
